The invention injection relates to a concrete geupgyeol admixture for, the total alkali content of 1.0% by weight or less as the spray concrete geupgyeol admixture for a liquid, to the general formula (I) of the poly-sulfated aluminum silicate the main component in said polyester to the amorphous aluminum hydroxide as a sub-component sulfate, aluminum silicate, and the injection geupgyeol concrete admixture for the content of the whole aluminum oxide contained in the amorphous aluminum hydroxide in the range from 6 to 17% by weight:; Formula 1; [Al a (OH) b ( SiO 2) c (SO 4) d] N; (Wherein a is 1.0, b is 0.75 ~ 2.0, c is 0.0005 ~ 0.1, d from 30 to 1.12 and N is the value of the total molecular weight in the range of up to 10 5) Due to its construction better coagulation properties as a liquid and have early strength characteristics the stability is excellent and shows the possible long-term storage effect.
